Tire ideas

That should provide a nice 1/16"-1/8" thick coat of resin to stiffen the whole tire without adding as much weight as totally filling it.

I also thought about getting some plastidip (in a can, not the spray) and pouring it in there, but I don't think it will ever harden. I need something that needs to be mixed so it cures via chemical reaction rather than air-dry seeing as it will be contained inside the tire and airflow is minimal if any.

Even if you were able to distribute the resin or whatever evenly, you'd still have flimsy sidewalls. That would mean still running foams or using sprayfoam, both of which I think the point here is to avoid. Sprayfoam would probably require at least 4 holes inside the rim to get close to even, unless it was done first as mentioned. Still there is almost no way you'd be able to have both a balanced wheel and one that runs true... it seems to me. Balancing would be more difficult with either of the above ideas, I think, than it would be to do the old way. I've given quite a lot of thought to this and keep coming up empty.

Now if someone could make a sub-carcass type of molded piece that the tire glued onto completely (or almost completely) and then the tire & molded carcass assembly was glued onto the rim, maybe that would be something. Need something like thin lexan, but something that would not be attacked by the various glues.

And there would be many profiles for someone to have to mold for the various tire inners. The various shapes and sizes could be semi-universal I suppose but who is gonna invest in the idea......

Really shouldn't be this difficult
